During the carnot cycle the overall entropy

WebSep 12, 2024 · There is no net change in the entropy of the Carnot engine over a complete cycle. Although this result was obtained for a particular case, its validity can be shown to be far more general: There is no net change in the entropy of a system undergoing any complete reversible cyclic process. Webentropy change of the surroundings, dSsurr (or ∆Ssurr) explicitly depends on the path. We need both of these quantities in order to determine the entropy change of the Universe during a process: dSuniv = dS +dSsurr or Suniv = S + Ssurr. Therefore, in calculations of entropy changes for real processes, we take the following strategy:
